trust will?

[prball]

I'm trying to determine if my late mother's will is set up for a trust with executors being the beneficiaries. The states the names of the people who will be both the executors & trustees of the will (which are all 3 sons).
Here's the relevant wording used in the will:
'I give the residue of my estate ... and any property over which I have at my death any general power of appointment to my Trustees on trust for sale with power to postpone sale without liability for loss and such estate and the property which currently represents it is referred to in this will as "the Trust Fund". My trustees shall hold the Trust Fund upon trust for such of my sons [then names the sons] as are living at my death and if more than one in equal shares."
It then goes on to mention that the trustees will have "..full and unrestricted power of investing and transposing investments in all aspects as if they were absolutely entitled beneficially to the money liable to be invested"

Is this standard wording, or do I need to add any details about a trust into IHT400 (or other forms) regarding this?

It's fairly standard wording. Assuming all living children are over 18, I would not mention a trust.
